BOX-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 347,299, dated August10, 1886.

Application filed February l, 1886.

and it consists of the hoop-forming rollers and an adjustable concaveshoe mounted in boxes, in a suitable frame-work, and combined with adrum for receiving the material and mechanism for placing and securingthe bottom or top in position within the hoopor body (as it is beingformed) in a convenient position for nailing, all of which will be fullyand clearly hereinafter shown, described, and claimed, by reference tothe accompanying drawings,

- in whichforming-rollers.

Figure 1 is a side elevation of the machine, a portion of the arms ofthe large spur-wheel being broken away to show the mechanism behind itmore clearly. Fig. 2 is a side elevation of a portion of the upper partof the frame-work and a vertical section through the Fig. 3 is an endelevation showing the gearing and driving mechanism, and also thereceiving or nailing roller with a section of a cheese or other box hoopor body upon it and the bottom in the position in which it is nailed tothe hoopor body. Fig. 4 represents a front view of a portion of themachine, showing the forming-rollers and adjustable shoe; and Fig. 5 isa longitudinal central section through one of the forming-rollers,showing a suitable means for admitting steam thereto.

Heretofore it has been found impossible to form the bodies of cheese orother boxes so that they will retain their shape permanently after beingformed. The reason for this has been the use of green, wet, or steamedmaterial, which, when released from their forming force, will springback to their normal shape again, and also in forming them without usingsufficient compressing force.

of the machine.

Serial No. 190.451. (No model.)

\Vith my machine the material is not only slightly compressed and bent,but it is formed and compressed in a dry state at the same time withsufficient force to cause it to bend evenly and to retain its shape whenso bent.

In said drawings, 1 and 2 represent the frame It is madepreferably ofcastiron, as being the strongest and best material. The side 2 of theframe is made narrower, so as to leave room for taking the cheese orother box off-from the nailing-drum.

3 aud t represent the formi ug-rollers. They are mounted in boxes in theframe. The lower roller, 4, is set in the vertically-sliding boxes 5,and is made adjustable by means of setscrews 6one on each side of themachine. One or both of these rollers may be either plain or corrugated,so as to give a more uniform appearance to the surface of the articlewhen formed.

The driving shaft 7 is mounted in boxes 8, in the frame, and is providedwith the usual tight and loose driving-pulleys, 9 and 10, and also witha pinion, 11, which is adapted to gear in with the spur-wheel 12 on theshaft 13 of the upper roller, 3.

14 represents an adjustable shoe, made concave in the direction of itswidth. It is supported in boxes 15, in bearings 16, so that it may beturned thereon, and is firmly secured in such position, when turned, bymeans of the nuts 17, which are loosened when it is necessary to adjustit in this way, and is then rigidly secured by tightening them. Thisshoe is also capable of an adjustment toward or from the forming-rollersby means of the setscrew 18 and a series of thin removable plates, 19.(See Fig. 2.) It is also made adjustable vertically up or down, by meansof the setscrews 20 and 21. This adjustment is required, so as to adjustit for different kinds of material and for forming boxes of differentsizes. The receiving and nailing roller or drum 22 is mounted on ashaft, 23,which shaft is secured rigidlyto the side frame,'1. Thisreceiving-roller is made easily removable (so as to adapt the machinefor boxes or stock, or jackets for cans of different sizes) by drawingit off from the free end of the shaft 23, the side frame, 2, being cutaway, as shown, so as to admit of its removal.

On that side of the machine opposite side 2 is a pivoted swinging plate,21, secured by a shaft, (or pin,)23, to the base of the machine. It isprovided with a circular disk, 26, of the same size as the receiving andnailing roller 22, and is pivoted to the swinging plate 2t by a pin, 27,(see Fig. 8,) so it may turn easily on said pin.

Onthc base of the machine is rigidly sccu red, in any well-known way, abed-piece, 2S, having a series of vertical guidepins, 2!). These pinsare set in a circle, so that when the swinging plate 2t is turned down,as shown by the dotted lines 30 in Fig. 3, thedisk .26 will swing downwithin the circle of these pins. This diskis provided with a series ofsharppointed pins, 31, shown on the dotted-line representation of saiddisk 30 in Fig. 3.

The object of the guide-pins 25) is to permit the bottom 33 (shown alsoin Fig. 3) of the box to be readily set onto the disk 26 in exactly theright place, so it will be in the proper position against the receivingand nailing roller when turned up against it, to permit the body or hoopto be nailed on as it is being formed. The object of the pins 31. is toprovide the means for securely holding the bottom or top firmly in placewhile being nailed.

\Vith some kinds ofstock it is well to have i one or both of the formingand compressing rollers hot, as such stock after being so formed retainsits shape better than if formed when the rollers are cold. laccomplishthis by introducing a jet of hot steam into the rollers. (See .l ig. 5,in which is shown a section cut lengthwise through the center of theroller 4-, for instance.) is a hollow space within the roller. .\t theend of one of its journals, 36, is a small opening, 37, which passesnearly through the journal, and then bends at right angles and comesthrough the side of the tapering portion Ila. Over this tapering portionis tilted (steam -tight) at box, 39, leading to or connected with apipe, it), connected in any weltknown way to a steam-boiler. This box 39is kept to its place by a nut, 41. The outlet for the steam is shown at42; but it may be placed at any other point on the roller, and beprovided, if desired, with a plug or stopcock of any well-known construction. It will be seen from this construction that the parts 39 and 40remain stationary while the roller turns, and still keeps a tightjoint,so that the hot steam may be passing in and out of the roller while itis in operation; but the steam may be thus used or not, according to thecondition or kind of stock used.

If the stock be a little damp it is often well to lizat the rollers. Theupper roller, 3, is secured in place by caps 43 and bolts 41-, and theframe is secured and put together in the usual well-known way, so that afurther description of that portion of the machine is not required here.

The operation of the invention is as follows: The compressing andforming rollers 3 and 4 being adjusted so as to give the amount ofcom- 5moves forward.

pressing force required, and the shoe 14 being also adjusted to form thematerial to the size of the circle required or to the size of the box,the material 3; is now placed in between the forming and compressingrollers, (see Fig. 1,) and as the machine is started it passes in and iscompressed and bent at the same time as it It moves onto the receivingand nailing roller 22, (a bottom or top having been previouslypresseddown against and onto the pins 31 on the diskflti, and then swings upagainst the receiving and nailing roller.) The piece 34 is now nailedonto the bottom while it is being formed and set onto thenailing-roller, which is fitted to turn easily on its shaft, all ofwhich will be readily understood by reference to Fig. 1, where 135represents the nails as they are being driven. \Vhen the material haspassed through the forming roll ers and the two ends lap on thereceiving roller, (or drum) they are nailed togetherin the usual way andthe box is taken off. If it is desired to form the bodies or tubes onlyand nail them together, the receiving or nailing roller would be usedwithout the circular disk 26 and its operating parts. In this wayjackets for cans or other purposes can be made. If desired, the pins 29and base 28 may be dispensed with without leaving the machineinoperative; but in that case it would require more care to put thebottoms or tops on the disk 26, so as to bring them exactly in the rightplace to be nailed onto the body or covenhoop.
